Description
A combined search for standard model four-top-quark production in the single lepton plus jets and dilepton channels will be presented. The analysis utilises the 2015 dataset recorded by the CMS experiment at $\sqrt{s}$ = 13 TeV which corresponds to an integrated luminosity of 2.6 fb$^{-1}$. A scheme based on a boosted decision tree algorithm is used to select signal and suppress backgrounds. An upper limit on the cross section of four-top-quark production will be presented.
